We should already have support for most of the trigonometric functions
built into ARQ as extension functions -

Sure, so my claims are 1) this is a good PR :) and 2) if we want to offer
the kind of functionality that you are removing, that's cool, but we should do
it in some appropriate, public, maintainable way

@ajs6f It takes [a bit
more](http://www.movable-type.co.uk/scripts/latlong.html) than just sqrt() to
calculate great-circle distances between coordinates even within the same
coordinate system, e.g.

@osma Yeah, that's what I meant tho'-- use a calculation (via `BIND`, I
guess?) of the distance (and we have [â available to
use](https://jena.apache.org/documentation/query/library-function.html))

@ajs6f I'm not sure whether you can use ORDER BY in a case like this. It
would need a SPARQL function for calculating distances between coordinates, so
you could say, in effect, "order by distance from

Thanks @afs for the approval. I will wait a few more days and then merge
this, unless there are objections.
The only scenario I'm mildly concerned about is if someone performs a
spatial query
